I am trying for the first time to boot my Windows 8.1 laptop from the internal CD-DVD drive. I have a bootable CD in there, and yes, I do have the bios set with CDROM drive as first in the list to boot from. But when I try to boot from the CD, it won't boot, instead the computer gives me this message:
"ATAPI CDROM has been blocked by the current security policy."
(Its actually a DVD drive.) All it lets me do at that message is hit the Enter key to OK the message, and then it boots from the hard drive.
I have no idea where "security policy" settings are or what they are set for. What do I have to do to get this to boot?
This is a Gateway laptop, 2.2 MHz Intel Pentium processor, 4 GB RAM, 64 bit OS, with Windows 8.1 fully updated, and Windows Defender running and fully updated.
I have already looked everywhere I can find, but nothing seems to address this message or issue, as follows:
*I went to Help menu to look up "Security Policy." While the computer is giving me the message about "security policy," the Help menu has no idea what "security policy" is, it just comes up blank!
*I went to Control Panels/System and Security/Action Center/Change Windows Settings/Smart Screen/... All I found in there that might be involved is a setting to block anything downloaded from the Internet until I give administrator access. Well, the booting issue didn't allow me to give administrator access (yes, I am the administrator) when I tried to boot, I only could hit the enter key to OK. Nonetheless, I changed to: notify me but proceed (not a quote).
With that, I tried again, but it still would not boot from the CD, got the same message, so that setting is not it. I changed the setting back.
I see no other setting there that could be related by even a stretch. And the control panels should be dealing with the OS anyway, and this is happening while trying to boot from the OS on the CD, not the hard drive. That is, this is something in the root.
*I then went into bios area (UEFI Firmware) by sweeping in from the right and into Settings/Change PC settings ..., and found a tab in bios for Security. Looking there, there is a list of things, but it lets me access only "Supervisor Password." It was currently set as "clear," meaning no password. I left it as that -- surely I can't need a password just to boot from a CD, and the message I got in trying to boot from the CD did not allow me to enter a password.
Other settings in the Security tab were not accessible. The only ones they included that might be remotely related were:
*Password on Boot, which was set as no password. But again, the message I get with this issue does not ask for nor allow me to enter a password.
*Secure Boot Mode: Standard (It does not let me access to change that.)
Some others also were in the list that are not worth listing, not even vaguely related.
I then went into some other things elsewhere in the main settings called Startup Settings. The only thing in there that sounded the least bit vaguely related was "Enable boot logging." I punched F2 to go into that, but the machine instead restarted, and did not start from the CDROM, same message again. I went back to it, and it is still listed as Enable boot logging, does not instead say Disable - so I don't know if anything even got changed. I did not touch it again, left it as-is.
So, that's it. I've checked all the settings I know about. Nothing about this bit about "ATAPI CDROM has been blocked by current security policy."
I tested with two DVDs that I have booted from in the past on other Windows machines -- they also would not boot, but they did not give me that message.
I note, all three CDs/DVDs are being read fine by the DVD drive once the machine is booted in Windows 8.1 from the hard drive - so the issue is not that the DVD drive can't read the disks.
Where is this "security policy" set?! What do I need to do to get this to boot from the CD?

Hi,
So everything is back to normal... or at least working to your satisfaction ?
You seem to know more about manipulating your email than I do, but though I may be able to help by describing what my screen looks like !
I know how that kind of conversation goes... Not so much with Microsoft, but with my internet provider sometimes..
I have no idea what build my OS is, I don't no where to find that info. But it is Win10 Home, and it is fully updated as of yesterday, so there is no newer build to go to.
I have no idea where the videos came from, other than a download from the Web -- and surely they must have been from different places,but I have no recollection. It was years ago. I don't think it a permissions or licensing issue. The Get Info in Mac says permissions are that Everyone can read them, which means they can be played. My particular user (it is the administrator too) on Mac can Read & Write, which I guess mean I could even edit them. I note, it says they are "Kind: Quicktime Movie."
I don't have any other wmv files, so I can't test any others.
Other info:
My Quicktime on Mac is v. 7.7, about the same as on Windows.
Codecs: Windows Media Audio 9 Standard. Windows Media Video 9 Standard."
I found the tab for DirectX. It was on by default. I unclicked it and hit Apply, the OK. I tested, didn't play and same message. I turned DirectX back on.
Mine seems to be different from your player. Mine does NOT have Optimize at top left. It has other stuff.
I can try reinstalling Klite and try that player. However, since I can't play these in WMP, in VLC Player, or in Quicktime on Windows, I have to think the issue is with something not in the application but farther back in the OS that all the players use. So, I am doubtful it will work with the Klite player.
I note, when I had Klite installed, it put up a window about checking/fixing things. It said there were some kind of issue that I don't recall with about a half dozen items in the registry. It said something about left overs form previous something. It asked if I wanted Klite to kill out those registry items. I said no, because I don't want to mess with the registry without knowing what's what, and since Klite asked, it must mean even Klite thought it might be wrong. But, should I just reinstall it and let it kill those registry items?
I looked at some security tab (and various other tabs) on them, I think out of Properties, I don't know what anything in there is, but nothing looked questionable.
Hi,
To find what build you are using, type "winver" into the RUN when you right click on the Windows Icon on the lower left corner... It's probably 14393.***
QuickTime movies are a different file than .WMV.. It uses .MOV. I don't remember if QuickTime will play .WMV files or not... I haven't used\needed it for years..
When you checked the security tan in Win 10, did it say "Everyone" like your Mac did ? Click on the Advanced button at the bottom and then look near the top of the window that opens... It should list an "Owner" of the file..
Sometimes when you copy files from one machine to another, they won't open\play because the permissions are set to a different machine\user...
I have some mp3 files that I downloaded years ago that require a special player or license to play them... The original files will no longer play... Fortunately I converted the files when I could play them... The converted ones will play, but the originals will not...
Are you sure these are .WMV files, not .WMA or something else...
Just shots in the dark here... I don't actually have a clue as to why they won't play at this point...
BTW... I wouldn't allow K-Lite to delete any registry stuff at this point... You could try their played though... I have had occasions in which the Media Player Classic would play stuff that other players wouldn't...
Damn,. I wish we were in touch direct. MS is so horrible. It would not let me go from my Hotmail-Outlook here and reply without singing in when I got here. I never have to do that because I'm already singed in. Then, it would not produce the sign in page, just processed endlessly, I gave up after about 40 minutes. I'm giving up, will try later or tomorrow to get this posted.
First, to clarify, Get Info in Mac is the equivalent of Properties in Windows, although Properties includes more stuff that Get Info does.
Re the format, you raised the messy. On my Mac, these files do not have any extension on them, not sure why, they normally do, that can be optional though.
I know that .mov is the native Quicktime format. But in Get Info, as I showed you above, it while it says they are Quicktime Movies, it said the codec used is:
Codecs: Windows Media Audio 9 Standard. Windows Media Video 9 Standard."
So, it is saying wma and wmv, so that should mean a wmv video. (wmv video will use wma audio, right.)
I would be very surprised if the .mov format uses wmv codecs!
I fought and looked around to try to get something more definitive on that for these, but that's the best I could come up with.
I added the .wmv extension on the files, and they open and play in my Mac Quicktime fine. I then changed the extension to .mov, and they still open and play fine.
I tried it with no extension, with the.wmv extension and with the .mov extension on Windows, it won't play no matter. Actually, while the player would open and try to show the video with the extensions on in Windows, it would not do that with no extension on the file.
The will not play in VLC player no matter the extension on either Mac of Windows.
So who knows what any of that means, but in the end, the codes are wmv.
I add, some years back,a friend had e-mailed me some .wmv videos, can't remember if they were ones he made or ones he thought were funny and sent along. But I could not play them on my Mac. That might be when I got Flip4Mac in order to be able to play wmv videos. (And Flip4Mac is what allows me to convert these to another format with QT on Mac -- but it is adding a watermark.) Or maybe that is when I found Perian for add codecs. But the point is, I think that is why I can play these on Quicktime ion Mac but not on Windows. Oh, these are other videos than what my friend sent along, so no, I can't just ask him what he did with them; the issue with wmv arose with his, and that made me hunt for a solution for that..
Re Klite and the Registry stuff, OK, you agree, don't do it, not without already know you want to delete those. I kind of thought coming from Klite, they might be identifying some items that are actually causing this issue.
Regarding permissions:
On Windows, in Properties, and Advanced, it labels all in the list as Allow. And everyone is listed in Groups and Users: System, the user, and the administrator. So, no permission restrictions at all.
And these aren't going to have any licensing issue to play only on Mac. As for the application, they don't play in QT on Windows but they do on My Mac (probably because I added Flip4Mac).
Hi,
You might try giving them the extension .wma in Windows and see what happens, or maybe even .mpg... just in case...
As far as K-Lite goes, it may be correct that there are residual files from some uninstalled program or something... I would have no problem correcting the problem if it deleted something I actually needed... Not so easy for you as it requires reloading an image..
It is possible that the files were created\modified with a compression that is not being recognized on the Windows machine... Even though the files may be .wmv for instance, there are multitudes of compression methods...
For instance... I have a program called Magix Edit Pro 14... I can output a file in a lot of formats, one of which is .mp4..
If I output a .mp4 with default settings WMP will play it... If I set it to output .mp4 at 3,000 bps instead of the default 768bps, WMP won't play it.. VLC will..
If I use a newer Edit Pro 17, WMP will play ANY of it's bps settings... The point being that there are variables within the actual file type that can cause issues...
It still may be Permissions... You mentioned that "Everyone" was listed in the Mac, but not Windows... That may be the issue right there...
You could try adding "Everyone" to the Windows List, or you could try making a copy of one of the files and changing the Ownership to you, it is not already...
It's not hard, but it can be a bit complicated... Here are some notes I made for another thread concerning Permissions... They may be for Win 8, but will work for Win 10... Some of the tabs may be a bit different, but not to hard to figure out...
If you are already listed in the 1st screen of the permissions, go to the Taking Ownership part... You could try adding "Everyone" to the list, but changing the Ownership to your name may be the best bet..
Here goes with the notes...
It is possible to Change Ownership of any drive, folder, or file (Exceptions with some system files) by right clicking on it, select Properties, and then the Security Tab at the top.
It is also possible to modify permissions, and add a user with permissions. This may be good enough to solve your problem, but you may need to change OWNERSHIP...which I always do on my machine.
To add a user, click on EDIT and select ADD....then
Change Ownership and add OwnerName as a USER
Select Security Tab and then ADVANCED at the bottom.
Here you can edit the permissions for existing users and\or add another..
Click Owner Tab at the top and select the User (you) that you want to take Ownership.
If it is not on the list...
Now select the Permissions Tab
ADD if not and steps 3-5 above
If the new OWNER doesn't appear on the 1st list you see after clicking the Security Tab now, use the first set of instructions to EDIT and Add a User.
